Title: Optical disk
Inventor: AZUMA KOICHI
IPC: G11B7/24079
Filed: 1985-01-08
Abstract: PURPOSE:To improve the fluidity of the resin flowing on the surface of a master disk and both the optical characteristics and the mass productivity of an optical disk, by using a master disk for optical disk which has a rectangular or trapezoi dal sectional form containing >=2 stages at the digital signal part. CONSTITUTION:The 1st photoresist 13 having the ordinary sensitivity to a specific laser for exposure and the 2nd photoresist 14 having the sharp sensitiv ity are coated successively on a glass master disk 8. Then the laser is irradiated to those photoresists for exposure and development. Thus it is possible to obtain a rectangular sectional form having two stages at a digital signal part 15. Then a metallic thin film of Ni of formed on the disk 8 by a vapor deposition process, etc. and then a nickel plating layer 17 is formed. The disk 8 is removed for production of a master disk 18 for optical disk. This disk 18 contains a rectangular sectional form having two stages at the part 15. Thus the resin flows smoothly when an optical disk is produced. This improves the optical characteristics of a resin base board 22. Then a reflecting film and a protecting film are formed for production of an optical disk.

Title: Voltage controlled oscillator
Inventor: YUSA MASAAKI
IPC: H03L7/08
Filed: 1988-01-08
Abstract: PURPOSE:To vary the frequency over a wide range by an input control voltage by devising a positive feedback gain of an emitter coupling multivibrator circuit so as to be always constant independently of the oscillated frequency and using the result as an output signal. CONSTITUTION:TRs 93-95, 97, 99 repeat ON/OFF operation according to a voltage at a terminal 33 and a voltage across a timing capacitor 106 shows a triangle wave to keep the oscillation. The oscillated frequency F is selected as F=I1/(4.C VD). The frequency F is given by a differential gain of the emitter coupling amplifier (comprising TRs 101, 102, 103) constituting a constant current I0 branch circuit with respect to an input control voltage V1 and shows an exponential functional change. In this case, the positive feedback gain giving the oscillation of the emitter coupling multivibrator circuit 30 depends only on the constant current 10 independently of the value of a current (I0-I1) branched to an emitter coupling differential circuit 37 and becomes a constant amplitude proportional to a value RL.I0.

Title: Circuit for detecting code rule violation
Inventor: SUEHIRO YOSHIKAZU
IPC: H03M13/00
Filed: 1985-01-10
Abstract: PURPOSE:To prevent an abnormal output after application of power by inhibiting detection of code rule violation until a code rule violation detecting signal shows a normal value after application of power. CONSTITUTION:When a power 55 is applied, a level of a preset enable terminal 41 of a counter 31 goes to L for a certain period by an integration circuit comprising a resistor 50 and a capacitor 51 to set a value set by preset inputs 39, 40, 41 of the counter 31. In this case, logical '0' is outputted to an input 33 of an AND gate 28 and a coded mark inversion CMI code rule violation rule detection signal 9 is logical '0' regardless of outputs 15-18 of a shift register SR2. The state that the signal 9 indicates logical '0' continues until 4 clock signals 8 are transmitted. In this state, the input 33 of a gate 28 goes to logical '1' and the signal to the input 32 is received. Since outputs 15-18 of the SR2 are arranged at a value when an NRZ data 7 is logical '1', the signal 9 is a normal signal.

Filed: 1981-01-08
Abstract: PURPOSE:To automatically determine the supplied electric power for a wire-cut spark erosion machine, by entering the quality of a work and the specifications of the machining wire into an information processing unit to determine the machining electric power. CONSTITUTION:Driving sections 9, 10 are operated through a controller 8 to  move a table 5 on which a work 4 is set.

Abstract: PROBLEM TO BE SOLVED: To reduce a clock pulse delay and to enable a high speed drive by leading a wiring for applying a driving pulse to a CCD register from a midway of the CCD register. SOLUTION: A first and a second wiring layers 4, 5 and a ground wiring layer 6 are formed from e.g. a first Al layer, and a third and a fourth wiring layers 7, 8 are formed from e.g. a second Al layer and connected to the first and the second wiring layers 4, 5 through contacts 3, respectively, the wiring of a horizontal CCD register 1 is composed of metal layers of the first and the second Al layers, the third and the fourth wiring layers 7, 8 composed of the second Al layer are led from a midway of the CCD register, this permitting the clock voltage to be applied also from the midway of the horizontal CCD register. Thus it is possible to greatly suppress the delay of a driving pulse due to the load capacitance and wiring resistance in the CCD register and drive the horizontal register of large-area CCD elements at a high speed and low voltage.
